Question

a group of rabbits lives in a forest. the ground used to be dark - brown soil. due to climate change, it has changed to light - colored rocks and sand. most rabbits had dark - brown fur. however, some rabbits were born with light - colored fur because of genetic variations. over time, more rabbits had light - colored fur. what is the most likely explanation for the trait shift within the rabbit population? why did light - colored fur become more common in the rabbit population?
the rabbits developed light - colored fur because the environment changed.
the rabbits with light - colored fur survived better and had more babies like them.
the rabbits decided to have babies with light - colored fur to survive better.
the rabbits all started having light - colored fur because of a sudden gene change.

Explanation:

This is an example of natural selection. Rabbits with light - colored fur had a survival advantage in the new environment (light - colored rocks and sand) as they were better camouflaged. They were more likely to survive and reproduce, passing on the genes for light - colored fur to their offspring.

Answer:

The rabbits with light - colored fur survived better and had more babies like them.
